MOLDED COAL, MANUFACTURING METHOD AND MANUFACTURING APPARATUS THEREFOR, AND MOLTEN IRON MANUFACTURING METHOD

摘要

Molded coal, a manufacturing method therefor, and a molten iron manufacturing method are provided. The molded coal is charged in the dome part of a melting gasification furnace, in an apparatus for manufacturing molten iron, and is rapidly heated, wherein the apparatus for manufacturing molten iron comprises: i) the melting gasification furnace in which reduced iron is to be charged; and ii) a reduction furnace connected to the melting gasification furnace and providing reduced iron. The molded coal manufacturing method comprises: i) a step of providing fine coal; ii) a step of providing a mixture by mixing the fine coal and a binder; iii) a step of providing molded coal by molding the mixture; and iv) a heat treatment step of increasing compressive strength by heating the molded coal.
